Wireless perimeter protection

The installation of large-scale perimeter protection has, until recently, been costly and time-consuming. However, with the availability of Optex’s wireless range of perimeter protection products, the securing of correctional facilities, mines, storage and impound yards, electrical substations, container depots, oil and gas refineries and other demanding premises will no longer be onerously expensive or labour-intensive.

Included in Optex’s new range is the SL-350 QFR, a 350-foot or 100-metre battery-powered photoelectric detector, which brings with it “significant cost savings for installers and interrogators” compared with traditional hardwired systems, says Elvey’s national sales manager, Ingo Mutinelli. “What is more, it offers a major benefit to end users in the form of less downtime to business operations since installation does not require trenching or wiring.”

Mutinelli lauds the detector for its high performance and large distance protection, saying it is the perfect way to lower labour costs and installation. “And despite its simplicity and flexibility, it is one of the most intruder detection sensitive systems available on the market today.”

Another of Optex’s new products, which form part of the Optex BoundaryGard family, is its new Smart Line Series of Quad technology, battery-operated active beams. Designed specifically to meet growing demand for easy instalment and cost-effective perimeter security, Mutinelli says the beams require minimal physical cabling – a boon for remote or difficult to access facilities. Available in two options, namely the standard SL-QNR and the top-end SL-QFR, which comprises four channel beams and variable frequencies, the units can be mounted on walls, poles or housed in 1,75-metre or 3-metre overt towers. The tower configurations can, in turn, be modified for single or multi head installations or back-to-back pole mounting.

For optimum results, he recommends the use of Optex’s high-grade aspherical lenses, which deliver best spread and strength over a 100-metre detection range but can still achieve acceptable results over far greater distances.

Easy integration

Designed for easy integration with most leading wireless and GSM transmitters, Optex’s Sniper Viewfinder employs advanced alignment technology designed to improve both reliability and intruder detection capabilities. Further, the innovative product uses a telescopic lens to order to deliver the highest possible visibility and magnification for optical alignment purposes. Even when the detection distance is extensive, the Sniper Viewfinder helps optimise the installation far quicker than most other solutions, he avers.

The unit’s capabilities are supported by a battery life of approximately four years, thanks to the low current consumption in both receiver and transmitter. It operates optimally between temperatures of -20° and 60°C, and, as evidenced by its IP65 protection rating, enjoys a high level of protection against insects, dust, sand and humidity up to 95%. Bird protection is also available through the use of a special bird cap, which will not only limit false alarms caused by small animals but will also deflect rain and snow.

According to Mutinelli, the unit offers a number of outputs, including alarm, D.Q circuit (environmental disqualification), low battery and tamper trigger and indicators that highlight alarms, levels, power and low battery. To make life even easier for installers, he says Optex has also designed a Beam-Alignment unit which automatically aligns the optical axis with the receiver.
